手势识别器在iphone中的疑惑

Question

我知道在ios中处理手势，但是可以为动作实现DoubleTapGesture吗？ 这意味着

UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeGesture:)];
    swipeGesture.direction = UISwipeGestureRecognizerDirectionRight; // or whatever
    [table addGestureRecognizer:swipeGesture];
    [swipeGesture release];
    UISwipeGestureRecognizer *swipeGestureleft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeGestureleft:)];
    swipeGestureleft.direction = UISwipeGestureRecognizerDirectionLeft; // or whatever
    [table addGestureRecognizer:swipeGestureleft];
    [swipeGestureleft release];

我们可以通过这种方式左右滑动，但我希望DoubleTap手势像上面的代码一样执行操作。 提前致谢。

您可以为此配置UITapGestureRecognizer：

UITapGestureRecognizer *dblTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];
dblTap. numberOfTapsRequired = 2;
[table addGestureRecognizer:dblTap];
[dblTap release];
